Computed tomography imaging characteristics of canine nasal chondrosarcoma.

OBJECTIVES: To describe the CT appearance of canine nasal chondrosarcoma and compare calcification patterns with those described in humans. MATERIALS AND METHODS: CT examinations of dogs with biopsy-confirmed nasal chondrosarcoma were retrospectively reviewed and evaluated, including description of calcification patterns. RESULTS: Major findings are consistent with the previously described CT appearance of canine nasal tumours. Additionally, calcification patterns described as features of human nasal chondrosarcomas were also identified. CLINICAL SIGNIFICANCE: Findings may help prioritise differential lists of destructive nasal masses seen on CT in dogs.
